Mill (grinding)
SAG mills are primarily used at gold, copper and platinum mines with applications also in the lead, zinc, silver, alumina and nickel industries. Tower mill [ edit ] Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a grinding process.

Gold extraction
Larger process plants have a lower operating cost per unit weight of material than a smaller plant using similar processes, but they also have a larger initial capital cost. For reference, a 1 Mt/a mill will have a capital cost within $25,000 /t/h and $50,000 /t/h.

How Gold Is Mined | Gold Mining Process | World Gold Council
Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly. On average, it takes between 10-20 years before a gold mine is even ready to produce material

The Metallurgy of Cyanide Gold Leaching
Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.

Gold CIL & CIP Gold Leaching Process Explained CCD
The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks.
